GroupLayout - Unable to add JPanel to JPanel

[modsiw]

Is there a reason I should be unable to add a JPanel to a JPanel with layout = GroupLayout?

I get the following exception in the eclipse .log file when I attempt it.

Code: Select all

java.lang.IllegalStateException: Container should be created.

Is there a reason I should be unable to add a JPanel to a JPanel with layout = GroupLayout?

No reason at all as it works fine on my end.

It would be helpful to see an actual example.

Sadly there isn't too much to show. Due to fail to create the sub-JPanel, no code is generated.

Below is an entire test class.
My eclipse preferences export.
And a screen capture of the error.

The stack trace is the same as in the OP.

Code: Select all

package com.floorsoft.floorwizard3.kiosk.forms;

import javax.swing.GroupLayout;
import javax.swing.JComponent;
import javax.swing.JPanel;
import javax.swing.LayoutStyle;

public class test21 extends JPanel
{

  /**
   * Create the panel
   */
  public test21() {
    super();
    GroupLayout groupLayout = new GroupLayout((JComponent) this);
    groupLayout.setHorizontalGroup(
      groupLayout.createParallelGroup(GroupLayout.Alignment.LEADING)
        .addGap(0, 994, Short.MAX_VALUE)
    );
    groupLayout.setVerticalGroup(
      groupLayout.createParallelGroup(GroupLayout.Alignment.LEADING)
        .addGap(0, 680, Short.MAX_VALUE)
    );
    setLayout(groupLayout);
  }

}

Preferences can not be attached due to format restrictions of the forums.

If desired, I'm more than happy to forward via email etc.

You can attach any file as long as you zip it.

Give this another try with the latest Swing Designer build.
